How many ions are produced from the complex, Co(NH_(3))_(6)Cl_(2) in solution ?

Answer»

6
4
3
2

Solution :COORDINATION number of cobalt =6. HENCE, the complex is `[Co(NH_(3))_(6)]Cl_(2)`. It ionizes in the solution as :
`[Co(NH_(3))_(6)]Cl_(2)overset(+aq)rarr[Co(NH_(3))_(6)]^(2+)+2Cl^(-)`
Thus, THREE ions are produced.
